摘要： A vacuum fluorescent display includes a front glass member, substrate, phosphor film, an electron-emitting portion, electron extracting electrode, and insulating support member. The front glass member has light transmission properties at least partly. The substrate opposes the front glass member through a vacuum space. The phosphor film is formed on that surface of the front glass member which opposes the substrate and has a predetermined display pattern. The electron-emitting portion is mounted on the substrate to oppose the phosphor film, and has an electron-emitting surface corresponding to the display pattern. The electron extracting electrode is arranged in the vacuum space between the electron-emitting portion and the phosphor film to be spaced apart from the electron-emitting portion by a predetermined distance. The insulating support member is formed on the substrate and adapted to support the electron extracting electrode and divide the electron-emitting surface of the electron-emitting portion into a plurality of regions.

摘要： A vacuum fluorescent display includes a cathode electrode, grid electrode, anode electrode, at least one envelope, phosphor screen, and cap. The cathode electrode emits electrons. The grid electrode extracts the electrons from the cathode electrode. The anode electrode accelerates the electrons extracted from the cathode electrode. The envelope accommodates the cathode electrode, grid electrode, and anode electrode in a vacuum space and has a phosphor screen plate having light transmission properties. The phosphor screen is formed on an inner surface of the phosphor screen plate of the envelope and adapted to emit light upon bombardment of the electrons accelerated by the anode electrode. The cap is made of an X-ray shielding material and supported outside the envelope so as to surround the phosphor screen plate of the envelope through a gap. The cap has a light exit portion from which the light emitted from the phosphor screen emerges through the phosphor screen plate of the envelope.

摘要： Disclosed is an electrode for an electron source, a method for producing the same, and an electronic tube using the same which provide a decreased thickness of an electron emitting source, and an improved current distribution percentage. The electronic tube comprises a substrate, an electron emitting source area formed on the substrate, and a shield area around the electron emitting area. The shield area is formed of a material that does not produce an electron emitting source, when the electron emitting source is produced by a dry method. As a result, if a space between an electron drawing electrode and the electrode for the electron source is narrow, the percentage of anode current increases in the total current, thereby improving the current distribution percentage.

摘要： A film (7) is formed by electrodeposition, thermal CVD, or spraying. After that, the film is irradiated with a laser beam. Carbon nanotubes that form the film (7) are disconnected by laser irradiation, so that the density of the carbon nanotubes is optimized. When the film (7) is formed in this manner, stable emission can be obtained from a cathode structure (5).

摘要： A method of manufacturing an electron-emitting source includes first to third steps. In the first step, a cathode structure made of a metal containing any one of ion, nickel, cobalt, and chromium is heated to a first temperature in a reaction furnace to which a carbon source gas has been introduced, to form a plurality of first carbon nanotubes on the cathode structure by chemical vapor deposition. In the second step, the metal serving as a material of the cathode structure is deposited on at least either one of the cathode structure and the plurality of first carbon nanotubes, to form a catalyst metal layer. In the third step, the cathode structure including the catalyst metal layer is heated to a second temperature higher than the first temperature in the reaction furnace to which the carbon source gas has been introduced, to form a plurality of second carbon nanotubes which are thinner than the first carbon nanotubes on the catalyst metal layer by chemical vapor deposition. An electron-emitting source is also disclosed.
